Metal Components
Failure to clean dirt from a metal band can lead to formation of rust, even if the x
band is stainless steel or plated. If the watch is exposed to sweat or water, wipe it
thoroughly with a soft, absorbent cloth and then store it in a well-ventilated location
to dry.
To clean the band, use a soft toothbrush or similar tool to scrub it with a weak x
solution of water and a mild neutral detergent. Take care to avoid getting solution on
the watch case.
Bacteria and Odor Resistant Band
The bacteria and odor resistant band protects against odor generated by the x
formation of bacteria from sweat, which ensures good comfort and hygiene. In order
to ensure maximum bacteria and odor resistance, keep the band clean. Use an
absorbent soft cloth to wipe the band clean of dirt, sweat, and moisture. The bacteria
and odor resistant band suppresses the formation of organisms and bacteria. It does
not protect against rash due to allergic reaction, etc.
E-67
Natural Leather and Imitation Leather Bands
Allowing the watch to remain in contact with other items or storing it together with x
other items while it is wet for long periods can cause the color of the other items
to transfer to the natural leather or imitation leather band of the watch. Be sure to
dry off the watch thoroughly before storing it and make sure it is not in contact with
other items.
Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for x
long periods or failure to clean dirt from a leather band for long periods can cause it
to become discolored.
Important!
Subjecting a natural leather or imitation leather band to rubbing or dirt can cause x
color transfer and discoloration.
E-66
Leaving the watch where it is exposed to direct sunlight (ultraviolet rays) for long x
periods or failure to clean dirt from the watch for long periods can cause it to
become discolored.
Friction caused by certain conditions (frequent external force, sustained rubbing, x
impact, etc.) can cause discoloration of painted components.
If there are printed fi gures on the band, strong rubbing of the printed area can cause x
discoloration.
Failure to clean dirt from the watch for long periods can cause fl uorescent color to x
fade. Wash dirt off with water as soon as possible and then dry the watch.
Semi-transparent resin parts can become discolored due to sweat and dirt, and if x
exposed to high temperatures for long periods.
Contact an authorized CASIO Service Center to have resin components replaced. x
Note that you will be charged for replacement costs.
E-65
Electrostatic charge can cause the display to go blank momentarily or cause a x
rainbow effect on the display.
Chemicals
Do not allow the watch to come into contact with thinner, gasoline, solvents, oils, or x
fats, or with any cleaners, adhesives, paints, medicines, or cosmetics that contain
such ingredients. Doing so can cause discoloration of or damage to the case, resin
band, leather band, and other parts.
Storage
If you do not plan to use the watch for a long time, wipe it thoroughly free of all dirt, x
sweat, and moisture, and store it in a cool, dry place.
Resin Components
Allowing the watch to remain in contact with other items or storing it together with x
other items for long periods while it is wet can cause the color of the other items
to transfer to the resin components of the watch. Be sure to dry off the watch
thoroughly before storing it and make sure it is not in contact with other items.
E-64
Impact
Your watch is designed to withstand impact incurred during normal daily use and x
light activity such as playing catch, tennis, etc. Dropping the watch or otherwise
subjecting it to strong impact, however, can lead to malfunction. Note that watches
with shock-resistant designs (G-SHOCK, Baby-G, G-ms) can be worn while
operating a chain saw or engaging in other activities that generate strong vibration,
or while engaged in strenuous sports activities (motocross, etc.).
Magnetism
Though your watch normally is not affected by magnetism, very strong magnetism x
(from medical equipment, etc.) should be avoided because it can cause malfunction
and damage to electronic components.
Electrostatic Charge
Exposure to very strong electrostatic charge can cause the watch to display x
the wrong time. Very strong electrostatic charge even can damage electronic
components.
E-63
Deterioration, rust, or corrosion of the band can cause it to break, which may result x
in the watch falling off your wrist and becoming lost. Be sure to take good care of the
band and keep it clean. Should you notice any breakage, discoloration, looseness
or other problem with the band, immediately contact your original retailer or an
authorized CASIO Service Center to have it checked, repaired, or replaced. Note
that you will be charged for any repair or replacement of the band.
Temperature
Never leave the watch on the dashboard of a car, near a heater, or in any other x
location that is subject to very high temperatures. Do not leave the watch where it
will be exposed to very low temperatures, either. Temperature extremes can cause
the watch to lose or gain time, to stop, or otherwise malfunction.
Leaving the watch in an area hotter than +60°C (140°F) for long periods can lead to x
problems with its LCD. The LCD may become diffi cult to read at temperatures lower
than 0°C (32°F) and greater than +40°C (104°F).
E-62
Some water-resistant watches come with fashionable leather bands. Avoid x
swimming, washing, or any other activity that causes direct exposure of a leather
band to water.
The inside surface of the watch glass may fog when the watch is exposed to x
a sudden drop in temperature. No problem is indicated if the fogging clears up
relatively quickly. If the fogging does not clear or if water has gotten into the watch,
take it in for repair immediately.
Continued use of the watch with water inside can result in damage to electronic and x
mechanical components, the face of the watch, etc.
Band
Tightening the band too tightly can cause you to sweat and make it diffi cult for air x
to pass under the band, which can lead to skin irritation. Do not fasten the band too
tightly. There should be enough room between the band and your wrist so you can
insert your fi nger.
E-61
Do not use this watch for scuba diving or other types of diving that requires air tanks. x
Watches that do not have WATER RESIST or WATER RESISTANT marked on the x
back cover are not protected against the effects of sweat. Avoid using such a watch
under conditions where it will be exposed to large amounts of sweat or moisture, or
to direct splashing with water.
Even if a watch is water-resistant, do not operate its buttons or crown while it is x
submersed in water or wet.
Even if a watch is water-resistant, avoid wearing it in the bath or in areas where x
detergents (soap, shampoo, etc.) are being used. Such conditions can reduce water
resistance.
After submersion in seawater, use plain water to rinse all salt and dirt from the x
watch.
To maintain water resistance, have the gaskets of your watch replaced periodically x
(about once every two or three years).
A trained technician will know how to check your watch for proper water resistance x
whenever you have its battery replaced. Battery replacement requires the use of
special tools. Always request battery replacement from your original retailer or from
an authorized CASIO Service Center.

This type of test battery may go dead quicker than the normally rated battery life x
as noted in the User’s Guide. Note that you will be charged for replacement of this
battery, even if replacement is required within the watch’s warranty period.
Low Battery Power
Low battery power is indicated by large timekeeping error, when display contents x
are dim, or when the display does blank.
Operation while battery power is low can result in malfunction. Replace the battery x
as soon as possible.
E-72
Skin Irritation
Individuals with sensitive skin or in poor physical condition may experience skin x
irritation when wearing a watch. Such individuals should keep their leather band or
resin band particularly clean, or switch to a metal band. Should you ever experience
a rash or other skin irritation, immediately remove the watch and contact a skin care
professional.
Battery Replacement
Leave battery replacement up to your original retailer or authorized CASIO Service x
Center.
Have the battery replaced only with the type specifi ed by in this manual. Use of x
another type of battery can cause malfunction.
When replacing the battery, also request a check for proper water resistance. Note x
that you will be charged separately for water resistance inspection.
Initial Battery
The battery that comes loaded in your watch when you purchase it is used for x
function and performance testing at the factory.
E-71
Remember that you wear your watch next to your skin, just like a piece of clothing. x
Because of this, you should always keep your watch clean. Use a soft, absorbent
cloth to wipe off any dirt, sweat, water, or other foreign matter from the case and
band.
Dangers of Poor Watch Care
Rust
Though the stainless steel used for the watch is highly rust-resistant, rust can form x
if the watch is not cleaned after it becomes dirty. Failure of oxygen to come into
contact with the metal because it is dirty causes breakdown of the oxidization layer
on the metal surface, which leads to the formation of rust.
Even if the surface of the metal appears clean, sweat and rust in crevasses can x
soil the sleeves of clothing, cause skin irritation, and even interfere with watch
performance.
Premature Wear
Leaving sweat or water on a resin band or storing it an area subject to high moisture x
can lead to premature wear, cuts, and breaks.
E-70
User Maintenance
Caring for Your Watch
A dirty or rusty case or band can soil the sleeve of your clothing, cause skin x
irritation, and even interfere with watch performance. Be sure to keep the case
and band clean at all times. Rust tends to form easily after the watch is exposed to
seawater and then left without cleaning.
Sometimes a smudge like pattern may appear on the surface of a resin band. This x
will not have any affect on your skin or clothing. Wipe the band with a cloth to clean
it.
Keep a leather band clean by wiping it with a dry cloth. Both resin bands and leather x
band can become worn and cracked over time when subjected to normal daily use.
Should your band become badly cracked or worn, be sure to have it replaced with x
a new one. Request band replacement from your original retailer or an authorized
CASIO Service Center. Note that you will be charged for band replacement costs,
even if your watch is still covered by its warranty.
